Corrugated hoses are thin-walled, cylindrical components with a corrugated structure in their surface area. Annularly corrugated hoses are technically superior to helically corrugated hoses. Their profile direction perpendicular to the hose axis enables an undisturbed interface of the connection fittings and thereby increases the process stability during assembly and in service. In addition, annularly corrugated hoses do not produce torsion loads with increased pressure or pressure shocks. Thus, today annularly corrugated hoses are generally preferred.
Through their corrugated structure, metal hoses are flexible and pressure resistant. They are leakproof, temperature and corrosion resistant as well as torsionally rigid and are used in the following applications:
for transport of liquids and gases under pressure, as vacuum pipe, as economic, flexible connection for absorbing movements, heat expansion and/or vibrations plus, as filling hose.
When configured correctly, the metal hoses are robust and nearly maintenance-free components with a high degree of operational safety and a long service life.
